Ships the canonical label set and the classifier that labels newly-filed issues.

Additive only — never removes a label, never overrides a human's classification, silent when unsure, never fails an issue.

Also adds this repo's two new workflows to .github/workflows/actions.lock as []. That lock is keyed by workflow path and refuses any workflow it does not list — a startup_failure, which produces no check run and is therefore silent. gh actions-lock cannot add these: it records action versions, and both workflows deliberately use none.

See docs/LABELS.adoc in hyperpolymath/.git-private-farm.

Merge Risk: 🟡 Moderate · up to c8551

The PR adds automated label management and issue triage, but the current implementation may fail to create or update repository labels and may modify issues explicitly marked not to be automated. It is not merge-ready until these bounded correctness issues are fixed or explicitly accepted.

Pull Request Overview

The PR introduces an automated issue triage system. While the implementation complies with the 'Python-free' requirement and follows a canonical labeling strategy, there are critical issues that should be addressed before merging. Specifically, the reesc function in the jq script contains a logic error that will cause regex failures for titles containing special characters. Additionally, the required .github/workflows/actions.lock file is missing despite being mentioned in the PR description.

Automated quality checks are up to standards, but functional coverage is lacking; none of the critical test scenarios for inflection handling, tier enforcement, or drift detection have been verified. There are also systemic concerns regarding the observability of errors in the workflows and the performance of the label synchronization process, which currently runs serial API calls for over 240 labels.

About this PR

  • The PR description mentions adding new workflows to '.github/workflows/actions.lock', but this file was not included in the commit. Please ensure the lock file is updated to maintain the estate's security standards.
  • The label synchronization workflow performs serial API calls with a mandatory sleep; with over 240 labels defined, the workflow will take approximately 2 minutes to complete on every run. Consider if this can be optimized or if the frequency of runs should be restricted.

Test suggestions

  • Verify 'kwrx' and 'kwhit' functions correctly handle inflection stems like 'investigat' matching 'investigation' or 'investigating'.
  • Verify 'enforce' logic correctly drops lower-precedence labels when a tier's 'tier_max' is exceeded.
  • Verify 'bracket' function correctly parses and normalizes leading tag patterns like '[p0]' or '[gov]'.
  • Verify 'prefixrule' correctly handles conventional commit prefixes with scopes (e.g., 'feat(ui):').
  • Verify that presence of an existing label in a max-1 tier (e.g., 'type:bug') blocks the engine from suggesting another label in that same tier (e.g., 'type:enhancement').
  • Verify 'labels.yml' sync logic correctly identifies drift in label color or description and updates them via the 'gh' CLI.
  • Verify 'labels.yml' sync logic ignores labels in the 'frozen' list regardless of configuration drift.
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify 'kwrx' and 'kwhit' functions correctly handle inflection stems like 'investigat' matching 'investigation' or 'investigating'.
2. Verify 'enforce' logic correctly drops lower-precedence labels when a tier's 'tier_max' is exceeded.
3. Verify 'bracket' function correctly parses and normalizes leading tag patterns like '[p0]' or '[gov]'.
4. Verify 'prefixrule' correctly handles conventional commit prefixes with scopes (e.g., 'feat(ui):').
5. Verify that presence of an existing label in a max-1 tier (e.g., 'type:bug') blocks the engine from suggesting another label in that same tier (e.g., 'type:enhancement').
6. Verify 'labels.yml' sync logic correctly identifies drift in label color or description and updates them via the 'gh' CLI.
7. Verify 'labels.yml' sync logic ignores labels in the 'frozen' list regardless of configuration drift.

🔴 HIGH RISK

The reesc function fails to escape characters correctly because .c is not a valid field on the match object. Use .string to access the matched character to ensure proper regex escaping.

🟡 MEDIUM RISK

Suggestion: Avoid suppressing stderr for label management commands with 2>/dev/null. Silencing these outputs makes it difficult to diagnose failures (such as permission issues, invalid color codes, or API rate limits) in the GitHub Actions logs. It is safer to let errors be visible while still allowing the script to continue execution.

⚪ LOW RISK

Suggestion: Silencing jq errors with 2>/dev/null hides potential issues in the issue classification logic. During the initial rollout, seeing these errors in the CI logs will help verify the robustness of the classification script and the ruleset.

Suggested change
echo "no confident classification - leaving for a human"

Do not classify issues labelled status:do-not-automate.

If an issue is reopened with status:do-not-automate, a matching title can still produce labels such as bug. The workflow then edits an issue that the canonical label defines as excluded from bots and sweeps.

Proposed fix
-  | if ($matched | not) then []
+  | if ($have | index("status:do-not-automate")) then []
+    elif ($matched | not) then []
     # a type is mandatory
     elif ((($out + $have) | any(. as $x | $types | index($x))) | not) then []

Set the target repository for label mutations.

This workflow does not check out the repository. gh label create and gh label edit require local repository context or GH_REPO; GITHUB_REPOSITORY alone is not sufficient. Pass --repo "$GITHUB_REPOSITORY" to both commands.
